Kaddy is the study app that keeps high school together in one place: your classes, your grades, your due dates, and the tools to actually get the work done. SEE EVERYTHING AT A GLANCE Your grade average, streak, and what's due this week are the first thing you see. Assignments sort themselves by urgency, so the thing due tomorrow is always on top. NEVER MISS A DUE DATE Add homework in seconds. Type it, say it in plain English, or import it from a syllabus or a screenshot. Reminders land before deadlines. ON YOUR HOME SCREEN Widgets show your streak and what's due next, in your class colors. On the Lock Screen, a countdown to midnight shows until you've studied for the day. STUDY TOOLS THAT PULL THEIR WEIGHT Flashcards with spaced repetition that resurface a card right before you'd forget it. A quiz generator that turns your notes into practice tests. A grade calculator that tells you exactly what you need on the final. Focus timers, solo or with a friend. AN AI TUTOR THAT KNOWS YOUR CLASSES Ask Kaddy (Pro) explains what you're stuck on using what you're actually studying. Compass (Bloomer), our college & career planner, turns "I want to get into my dream school" into the classes and extracurriculars that get you there. STUDY WITH FRIENDS Friends, class leaderboards, group study rooms, and streaks that make showing up every day feel like winning. Kaddy is free to use. Optional Pro and Bloomer plans unlock more AI power, but streaks, reminders, and your planner never sit behind a paywall. Pro and Bloomer are auto-renewing subscriptions, billed through your Apple ID. Manage or cancel anytime in Settings › your name › Subscriptions.
